ios - 在 didSelectRowAtIndexPath 创建的 UILabel 在同一位置不断重复

Question

嗨，我对 UILabel 有疑问在 UITableView 重复相同的位置.

我有一个自定义单元格和三个 UILabels .我只在 cellForRowAtIndexPath 显示第一个标签另外两个在 didSelectRowAtIndexPath .

当我点击单元格时，我想再显示两个标签显示，但是当我滚动 TableView 时它们在同一位置重复。

请帮我

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"English";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    if (isSearchOn) 
    {
         static NSString *CellIdentifier = @"English";
         UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
         NSString *cellValue = _searchResult [indexPath.row];
         cell.textLabel.text = cellValue;
         [cell.textLabel setFont:[UIFont fontWithName:@"Helvetica LT Std" size:22]];
    }
    else
    {
        ConversationInEnglish *con = _conversationsInfosnew [indexPath.row];
        _englishLabel = (UILabel *) [cell viewWithTag:10];
        _englishLabel.text = con.english;
        [_englishLabel setFont:[UIFont fontWithName:@"Helvetica LT Std" size:22]];
        UIButton *starButton = [UIButton buttonWithType:UIButtonTypeCustom];
        starButton.frame = CGRectMake(0 , 0 , 60, 37);
        UIImage *btnImage = [UIImage imageNamed:@"star.png"];
        [starButton setImage:btnImage forState:UIControlStateNormal];
        starButton.tag = indexPath.row;
        cell.accessoryType = UITableViewCellAccessoryNone;
        cell.accessoryView = starButton;
    }
    return cell;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([self.expandedCellIndexPath isEqual:indexPath]){
    }
    else 
    {
        ConversationInEnglish *con = _conversationsInfosnew [indexPath.row];
        UITableViewCell *cell1 = [self.tableView cellForRowAtIndexPath:indexPath];
        _myanmarLabel = (UILabel *)[cell1 viewWithTag:222];
        _myanmarLabel.tag = indexPath.row;
        _myanmarLabel.text = con.myanmar;
        [_myanmarLabel setFont: [UIFont fontWithName:@"Masterpiece Uni Sans" size:16]];
        [cell1.contentView addSubview:_myanmarLabel];
        _tonebasedLabel = (UILabel *)[cell1 viewWithTag:333];
        _tonebasedLabel.tag = indexPath.row;
        _tonebasedLabel.text = con.tone_based;
        [_tonebasedLabel setFont:[UIFont fontWithName:@"Helvetica LT Std" size:15]];
        [cell1.contentView addSubview:_tonebasedLabel];
        _speaker = [UIButton buttonWithType:UIButtonTypeCustom];
        _speaker.frame = CGRectMake(100 , 80 , 150, 37);
        UIImage *btnImage = [UIImage imageNamed:@"speaker.png"];
        [_speaker setImage:btnImage forState:UIControlStateNormal];
        _speaker.tag = indexPath.row;
        [cell1.contentView addSubview:_speaker];
        self.expandedCellIndexPath = indexPath;
        self.expandedCellHeight = 110.0f;
    }
    [self.tableView beginUpdates];
    [self.tableView endUpdates];
}

创建 UILabel 的代码似乎不在您提供的代码段中，所以我不能确定这是您的问题，但请检查您的 UILabel 框架的原点是否靠得太近。其中一个原点可能需要增加其 x 值以分隔两个 View 。
